maybe an even easier way,,,,
go to this folder
\Game Guru\Files\audiobank\voices\todd
find the file ...
jetpack.wav
open it in any audio editing program and set the volume to 0
then save and replace the file with the zeroed volume one.
If you try the other methods....if you do a file verification all will be reset to original settings..im pretty sure.
